WATERWAYS across Southern Sydney could become protected areas in a marine park that stretches from Gosford to the southern tip of Royal National Park.
The National Parks Association (NPA) last week launched a world-first proposal to turn the waters surrounding a major urban centre into a marine reserve.
NPA marine project manager Nicky Hammond said the reserve would ensure the health of marine ecosystems.
"There are currently only two small marine protection areas in the entire Sydney area, one in Manly and Towra Point.''
She said that the proposal was for a "multiple use'' marine park, meaning that commercial and recreational fishing would be affected, but only in certain parts of the reserve.
Ms Hammond said it was not yet clear how waterways in Botany Bay and Bate Bay would be affected.
"We want to stress that there would be extensive community consultation about the marine zones and where fishing restrictions would apply,'' she said.
She said that if commercial fishermen were affected by marine park restrictions they would be compensated financially by the State Government.
Minister for Climate Change and the Environment Carmel Tebbut said the proposal had been referred to the Marine Parks Authority for their "consideration and advice''.
"While I welcome the report, I note that marine parks are not the only way to protect our precious marine environment,'' Ms Tebbut said.
"For example, in the Hawkesbury Shelf Bioregion, which extends from Wollongong to Newcastle, there are already 27 marine protected areas which include marine habitats.''
